Police responded shortly after 2:30 p.m. Friday to the center at 810 Western Park. They found two boys, ages 15 and 17, who had been shot. The boys were taken to the Regional Medical Center at Memphis in critical condition.

Investigators determined the boys were arguing with another group and the confrontation turned physical, according to a police affidavit. During the fight, a man nicknamed "Nu Nu" allegedly shot the boys.

It's unclear what started the confrontation.

"Nu Nu" was identified the next day in a police photo lineup. He was arrested Monday.

Phillip Lipsey, 18, was charged with two counts of aggravated assault.
